Description

Technical Field

[0001] The present invention relates to the technical field of core board stacking and separating mechanisms, and particularly relates to an automatic separating mechanism for the stacked incoming materials of core boards after PCB fusion. Background Art

[0002] PCB core board: Also known as the printed PCB core board, it is the provider of electrical connections for electronic components and can be used to carry a variety of electronic components.

[0003] In order to improve the production efficiency of multi-layer boards, factories have introduced and used PCB core boards formed by fusion and riveting technologies. Fusion boards and riveting boards generally have only a few connection points, and the connection points are only used for positioning. When the core board is relatively thick or the number of layers is slightly more, the strength of the connection points cannot support suction and transplanting.

[0004] Therefore, for the feeding of existing PCB core boards, manual feeding is usually adopted. Workers first place the stacked PCB core boards on the feeding station, take out the PCB core boards from the stacked materials and then position them on the positioning fixture. Then, the manipulator places the PCB core boards positioned by the positioning fixture onto the production line, and then manually takes out and stores the separator paper. Each time of feeding requires taking out the PCB core boards and the separator paper, with slow feeding speed and high labor intensity. Summary of the Invention

[0057] PCB core boards are stacked on the surface of the loading carrier plate F5; the loading carrier plate F5 can slide on the rollers F1 to reach a set position;

[0058] Then it is pushed into the interior of the chassis C by the trolley body F3; the upper loading elevator G gradually lifts the loading carrier plate F5 upward, so that the height of the topmost PCB core board is always kept consistent.

[0059] As a preferred embodiment of the present invention, the upper loading elevator G includes an upper loading vertical bracket G2, an upper loading lifting guide rail G1 fixed on the upper loading vertical bracket G2, and a lifting support bar G5 slidably connected to the upper loading lifting guide rail G1; the number of the lifting support bars G5 is two; two gaps are formed between the roller bracket F2 and the two support beams F4; the two lifting support bars G5 are respectively opposite to the two gaps; an upper loading lifting module G3 for driving the lifting support bar G5 to perform a lifting movement is fixed on the upper loading vertical bracket G2; the upper loading lifting module G3 has no essential difference from the prior art, so it will not be elaborated here; the upper loading lifting module G3 drives the two lifting support bars G5 to perform a lifting movement, and the number of the lifting support bars G5 is two, which can pass through the above gaps from bottom to top and lift the loading carrier plate F5.

The core board shoveling assembly H and the pressing plate lifting assembly can also separate the separator paper and press the separator paper tightly to prevent the separator paper from being taken away when the core board is taken out.

[0062] As a preferred embodiment of the present invention, the separator paper recycling mechanism B further includes a recycling linear module B4 and an outer box B5; a recycling box assembly B1 for collecting separator paper is arranged inside the outer box B5; a separator paper recycling assembly B3 placed on the top of the recycling box assembly B1 is connected to the recycling linear module B4; a recycling air rod B305 is provided on the separator paper recycling assembly B3; the pressing plate lifting assembly includes a pressing plate B306, and a recycling suction nozzle B307 is provided on the recycling air rod B305;

[0063] The recycling linear module B4 can drive the separator paper recycling assembly B3 to perform a translational movement, and can insert the pressing plate B306 into the lower surface of the topmost PCB core board, so that the topmost PCB core board is separated from the separator paper below. After the core board to be shoveled is taken out by the manipulator, the recycling air rod B305 is connected to a negative pressure device, and the separator paper is sucked by the recycling suction nozzle B307.

Finally, the separator paper is dragged into the recycling box assembly B1, the negative pressure of the recycling suction nozzle B307 is removed, and the separator paper falls into the recycling box assembly B1. In addition to realizing the function of core board separation, this structure can also recycle the separator paper into the recycling box assembly B1, reduce the labor intensity, and reduce the risk of the manipulator clamping the worker when taking out the separator paper.

[0064] A pressing plate lifting assembly is connected to the separator paper recycling assembly B3; both the recycling air rod B305 and the pressing plate B306 are connected to the pressing plate lifting assembly;

[0068] A handle B104 is fixed on the recycling box B102; a plurality of through holes are provided at the bottom of the recycling box B102; the through holes provide an exhaust channel when the first separator paper is put in, preventing a vacuum environment from being formed between the separator paper and the bottom surface of the recycling box B102, which is convenient for taking out the separator paper.

[0069] An iron block B103 is fixed on the recycling box B102; an electromagnet B7 is fixed on the outer box body B5; the electromagnet B7 is arranged opposite to the iron block B103; when the recycling box B102 slides into the designated position in the outer box body B5, the electromagnet B7 fits with the iron block B103, and the electromagnet B7 is energized to attract the iron block B103 so that the recycling box B102 is positioned in the outer box body B5 to prevent the recycling box B102 from sliding in the outer box body B5; when it is necessary to pull out the recycling box B102 from the outer box body B5, the electromagnet B7 is powered off, the iron block B103 and the recycling box B102 are no longer attracted by the electromagnet B7, and the recycling box B102 can be easily pulled out.

[0072] As a preferred embodiment of the present invention, the core plate transplanting manipulator includes a clamping and moving module E and a core plate clamping mechanism A connected to the clamping and moving module E; the clamping and moving module E has no essential difference from the existing linear module, so it will not be elaborated here;

[0073] The core plate clamping mechanism A includes a clamping fixing plate A1 and two clamping connecting plates A6; moving modules are connected between the clamping connecting plates A6 and the clamping fixing plate A1;

[0074] An elastic clamping component A7 is arranged on the clamping connecting plate A6;

[0075] The elastic clamping component A7 includes a lower clamping shovel A707 rotatably connected to the clamping connecting plate A6 and a lifting clamping module arranged directly above one end of the lower clamping shovel A707; a spring A703 is connected between the other end of the lower clamping shovel A707 far from the lifting clamping module and the clamping connecting plate A6;

[0076] The moving module can drive the two clamping connecting plates A6 to move closer to or away from each other, and perform two-direction movements of the two clamping connecting plates A6 in the lifting direction;

[0077] When the moving module drives the lower clamping shovel A707 to descend until the end of the lower clamping shovel A707 is directly below the PCB core plate to be grabbed, the moving module then drives one of the lower clamping shovels A707 (the lower clamping shovel A707 on the side where the PCB core plate to be taken is convex relative to the lower PCB core plate) to translate, insert the lower clamping shovel A707 between the misaligned positions of the PCB core plate and the lower core plate, and the lifting clamping module and the lower clamping shovel A707 cooperate to clamp and fix one side of the PCB core plate; then the moving module drives the other lower clamping shovel A707 to translate, the lower clamping shovel A707 is inserted under the PCB core plate to be grabbed, and the lower clamping shovel A707 elastically fits on the surface of the separator paper.

[0078] The separator paper applies pressure to the lower clamping shovel A707, causing the lower clamping shovel A707 to overcome the elastic force of the spring A703 and flip, so that the lower clamping shovel A707 is elastically pressed against the separator paper, avoiding rigid pressing and reducing the damage to the surface of the next PCB core board during material grasping.

[0079] A U-shaped part A705 is fixed on the clamping connection plate A6; a clamping rotating shaft A706 is rotatably connected to the U-shaped part A705; the clamping rotating shaft A706 is fixedly connected to the lower clamping shovel A707.

[0080] A clamping plate limit post A704 is connected to the U-shaped part A705; one end of the clamping plate limit post A704 is arranged on the upper surface of the lower clamping shovel A707 away from the lifting and clamping module.

[0081] In the empty clamping state, the acting force of the spring A703 causes the lower clamping shovel A707 to flip. By setting the clamping plate limit post A704 to limit the maximum flipping angle of the lower clamping shovel A707, the maximum flipping angle of the lower clamping shovel A707 downward is inclined and towards the side of the PCB core board.

[0082] The clamping plate limit post A704 is a bolt; a threaded hole matching the bolt is arranged on the U-shaped part A705; the bolt is threadedly connected to the threaded hole; by rotating the bolt, the bolt can be telescoped on the U-shaped part A705 to adjust the maximum flipping angle of the lower clamping shovel A707.

[0083] The cross-section of the end of the lower clamping shovel A707 close to the lifting and clamping module is conical; by setting the end of the lower clamping shovel A707 to be conical, it is easier to insert into small gaps.

[0084] The lifting and clamping module includes a clamping power cylinder A702 and an upper clamping block A701; one end of the clamping power cylinder A702 is fixed on the clamping connection plate A6; the upper clamping block A701 is fixedly connected to the other end of the clamping power cylinder A702; the upper clamping block A701 is arranged above the lower clamping shovel A707.

[0085] The clamping power cylinder A702 drives the upper clamping block A701 to move in a direction close to or away from the lower clamping shovel A707, and clamps and fixes the PCB core board between the upper clamping block A701 and the lower clamping shovel A707.

[0086] The moving module includes two transverse moving seats A8; clamping transverse moving modules A2 are arranged between the transverse moving seats A8 and the clamping fixing plate A1; a clamping lifting module is connected between the clamping connection plate A6 and the transverse moving seats A8; the clamping transverse moving module A2 is used to drive the transverse moving seat A8 to perform a translational motion to realize the overall translation of the elastic clamping assembly A7, and the clamping lifting module drives the clamping connection plate A6 to perform a lifting motion to realize the overall lifting motion of the elastic clamping assembly A7.

[0087] The clamping and lifting module includes a clamping and lifting electric cylinder A3, a clamping guide sleeve A4, and a clamping guide shaft A5; the clamping guide shaft A5 is fixed on a clamping connecting plate A6; the clamping guide sleeve A4 is fixed on a transverse movement base A8; the clamping guide sleeve A4 is slidably connected to the clamping guide shaft A5; both ends of the clamping and lifting electric cylinder A3 are respectively connected to the transverse movement base A8 and the clamping connecting plate A6; after the clamping and lifting electric cylinder A3 is started, it drives the elastic clamping assembly A7 on the clamping connecting plate A6 to move up and down along the linear direction of the clamping guide shaft A5.

[0088] The clamping and transverse movement module A2 is an electric cylinder.

[0089] When using the present invention, in the first step, PCB core boards are stacked on the surface of the loading and material-carrying plate; the loading and material-carrying plate can slide on the rollers to reach a set position;

[0090] Then it is pushed into the interior of the chassis by a trolley body; the loading and lifting module drives two lifting support bars to move up and down. The number of the lifting support bars is two, and they can pass through the above-mentioned gap from bottom to top and lift the loading and material-carrying plate, so that the bottom surface of the bottommost PCB core board is slightly lower than the material-shoveling plate and the pressing plate.

[0091] In the second step, after the material-shoveling translation cylinder is started, it can drive the material-shoveling translation plate to slide translationally, place a separator paper under the topmost core board of the material-shoveling plate, and then the material-pressing and lifting cylinder drives multiple material-shoveling plates on the material-shoveling lifting plate to move up and down. The material-pressing and lifting cylinder drives multiple material-shoveling plates on the material-shoveling lifting plate to move up and down to press down the separator paper and create an opening insertion gap between the core board and the separator paper, separating the core board from the lower separator paper; in this state, the pressing plate presses the separator paper to prevent the separator paper from being driven.

[0092] In the third step, the core board transplanting manipulator grabs a PCB core board separated from the material vehicle by the core board separation component and transports it to the discharging mechanism; after the discharging mechanism accurately positions the PCB core board, it is then transported to the loading station.

[0093] In the fourth step, the recycling air rod is connected to a negative pressure device, and the separator paper is sucked by the recycling suction nozzle. The recycling linear module drives the entire separator paper recycling component to move, so that the recycling suction nozzle drags the separator paper to separate from a PCB core board below. Finally, the separator paper is dragged into the recycling box component, the negative pressure of the recycling suction nozzle is removed, and the separator paper falls into the recycling box component.

[0094] In this mechanism, the core board and the separator paper are pre-separated by the core board separation component, and then the core board transplanting manipulator takes out the core board and places it on the fixture, and the core board separation component takes out the separator paper, which can realize the automatic separation of the core board and the automatic recycling of the separator paper, improve the loading efficiency of the core board and reduce the labor intensity.

[0095] The above are only the preferred embodiments of the present invention, so all equivalent changes or modifications made according to the structures, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
